Heating characteristics of medium frequency induction furnace
Regarding the rebar production line, the manufacturing process is as follows:
The steel is melted into molten iron in professional equipment, and then poured into a cast iron mold to form a billet. The slab is heated by various heating furnaces, and after passing through the continuous casting machine and continuous rolling mill, it becomes a new steel bar.
The electric furnace,furnace and induction furnace that we have been introducing to you can be regarded as a kind of equipment, that is, a heating furnace specially used to melt molten iron.
The principle of heating is to use the intermediate frequency magnetic field eddy current to melt various steel materials. The editor of Collective Red Teng will introduce the characteristics of this furnace to you.
The principle of intermediate frequency induction heating is electromagnetic induction, and its heat is generated in the workpiece itself. Ordinary workers can carry out the continuous work of the forging task ten minutes after going to work with the intermediate frequency electric furnace, and there is no need for furnace workers to burn and seal the furnace in advance.
Using the principle of electromagnetic induction heating, the heating speed is fast, so the oxidation of the steel is less. The oxidative burning loss of heating forgings is only 0.5%, the oxidative burning loss of gas furnace heating is 2%, and that of coal-fired furnace is 3%. Therefore, the intermediate frequency furnace heating process saves at least 20-50kg of steel raw materials per ton of forgings compared with coal-fired furnaces, and the utilization rate of steel can reach 95%.
Because the heating method is evenly heated and the temperature difference between the core surface is small, the life of the forging die is greatly increased in forging, and the surface roughness of the forging is also less than 50um. Gas heating saves 5% to 40% of energy.
The heating quality is good, which can reduce the scrap rate by 1.5%, increase the productivity by 10%~30%, and prolong the life of the mold by 10%~15%.
It is also important that the working environment of induction furnaces is better. For example, compared with coal furnaces, workers will no longer be roasted and smoked by coal furnaces under the scorching sun, which can greatly improve production efficiency.
It is because of these characteristics that our furnaces are used to smelt a variety of metals: pig iron, ordinary steel, stainless steel, tool steel, copper, aluminum, gold, silver and alloys. It can also be used for various heat treatments of metals, and has a wide range of applications.
